[PATCH 4.12 002/196] [media] ir-core: fix gcc-7 warning on bool arithmetic

[Greg Kroah-Hartman]

4.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Arnd Bergmann <arnd@xxxxxxxx>

commit bd7e31bbade02bc1e92aa00d5cf2cee2da66838a upstream.

gcc-7 suggests that an expression using a bitwise not and a bitmask
on a 'bool' variable is better written using boolean logic:

drivers/media/rc/imon.c: In function 'imon_incoming_scancode':
drivers/media/rc/imon.c:1725:22: error: '~' on a boolean expression [-Werror=bool-operation]
    ictx->pad_mouse = ~(ictx->pad_mouse) & 0x1;
                      ^
drivers/media/rc/imon.c:1725:22: note: did you mean to use logical not?

I agree.

Fixes: 21677cfc562a ("V4L/DVB: ir-core: add imon driver")
